ALFRED JAMES JUNG,

OF LONDON, ENGLAND.

CURTAIN, KEY, AND OTHER RING.

To all whom it may concern:

Be it known that I, ALFRED JAMES J UNG, a British subject, and a resident of London, England, have invented certain new and useful Improvements in Curtain, Key, and Other Rings; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of the specification, and to the characters of reference marked thereon.

This invention relates to curtain, key and other rings and refers to rings which are formed from or of a single piece of wire, rod or the like.

The chief object of the present invention is to provide for such rings a simple and efficient self-acting securing or fastening device formed in the body of the ring without protruding, projecting or loose parts and which will hold the meeting ends of the ring rigidly and against any lateral or longitudinal displacement or accidental disconnection.

According to the present invention, there is formed or furnished on each of the two ends of the material forming the ring, a transverse tooth or notch which is undercut or hooked and on one end is cut a short longitudinal notch or groove while on the other end is formed a longitudinal projection rib or ridge.

Referring to the accompanying drawings:

Fig. 1 shows a ring constructed in accordance with or embodying the present invention the ring being in the closed position.

Fig. 2 is a plan of Fig. 1.

Fig. 3 shows the ends of a ring in the open position.

Fig. t is an end view of one of the ends of the ring.

7 Fig. 5 is a similar View of the other end of the ring.

A and B are the undercut teeth.

0 is the longitudinal notch or cut, and

D is the longitudinal ridge or tooth.

The two ends of the ring E are cut through or formed at an angle (see Fig. 3) to the vertical plane, and across the ends are made the two transverse cuts A and B, one on each. end the out A being on the upper and the out B on the under side. Thus when the two ends are brought together these transverse cuts A and B overlay and interlock with the inclined faces of the two ends in close contact. These two interlocking teeth prevent the ends of the ring from being drawn apart.

On the end having the transverse cut A is the longitudinal notch or groove C which is of somewhat V-shape or its may have rounded or straight sides, and'on the other end having the transverse tooth or cut B is a rib, tooth or projection D which when the ends of the ring are brought together and the teeth A and B are interlocked, engage and prevent sidewise or late al movement of the ends of the ring.

The groove C may be formed by cutting, stamping or in any convenient manner, and the projection D may also be formed or produced by punching or stam 'iing a portion of the end of the ring.

\Vhen the ring is closed, as the parts of the fastening are formed in the body of the ring itself they are practically invisible and no parts protrude or project from the surface of the ring, the ends of which are firmly held against longitudinal or lateral displacement and also against accidental disengagement.

In the preferred embodiment of the invention as illustrated in the accompanying drawings the ends of the split ring have a tendency to flex radially out-ward, due to the resiliency of the material of which the ring is composed, but it will be apparent that this does nothing more than hold the transverse locking elements tightly in engagement with each other. \Vhen it is desired to open the ring nothing need be done except to place the thumb on one of the ring ends, the end having the tooth A thereon,

and press said ring end substantially radially inward. This simultaneously releases both sets of cooperating elements and permits the ring ends to move apart. Compared with most of the devices of the prior art it will be found that this construction possessest several advantages amongst which are the following: The ring is preferably made of a single piece of resilient material; the cooperating elements are formed integral with the ring itself; and, the latching elements are rigid and strong and are not very apt to become broken.

What I claim is 1. As a new article of manufacture, a one piece split ring of resilient material provided with a fastening means for the ring ends comprising two transverse and co-opllt) erating rigid teeth formed ne on each end end of the ring adapted to enter said notch to prevent lateral displacement of said ends.

2. As a new article of nianu'fac't'ure,a'o-ne' piece, split ring of resilient material, the

ends cf ther ing' being disposed at an acute" I r N being "disp'esed at an' angle t@ a l ne draxyn.
